Yay! Now to wait for the new receivers to come out

Thats laughable. Can any receiver handle the following.

• 4K@50/60, (2160p), which is 4 times the clarity of 1080p/60 video resolution
• Up to 32 audio channels for a multi-dimensional immersive audio experience
• Up to 1536kHz audio sample frequency for the highest audio fidelity
• Simultaneous delivery of dual video streams to multiple users on the same screen
• Simultaneous delivery of multi-stream audio to multiple users (up to 4)
• Support for the wide angle theatrical 21:9 video aspect ratio
• Dynamic synchronization of video and audio streams
• CEC extensions provides expanded command and control of consumer electronics devices through a single control point

So whats the point of 32 audio channels? How about 1536kHz audio sample frequency? Then you have 4K@50/60 which requires double the stream bandwidth, or twice the storage or CPU power? If one would take a step back and look at this from a commercial theater side, yes this simplifies cabling just like HDMI got rid of all those cables in a home theater.

But the big question is does HDMI 2.0 spec being released buy the consumer anything at this time or a year from now?

lol, isn't that why he said "Now to wait for the new receivers to come out"? Because none currently do?

I was agreeing with the poster, the situation is laughable, but also quite sad. Here we have the HDMI.org trying their darnest to keep ahead of technology, well congratulations they succeeded.

note this:

In line with HDMI 2.0 specs, the TX-L65WT600 will support 4K resolution at higher frame rates of 50fps and 60fps, bursting past the previous HDMI 1.4 limitations of 4096×2160 at 24fps or 3840×2160 at 30fps which would have put a dampener on fast-paced 4K content like live sports broadcast.

• 4K Fine Remaster Engine: upscales any sub-4K content to 2160p;
• 4K Intelligent Frame Creation: motion interpolates 60Hz to 120Hz (or 50Hz to 100Hz for us in the UK and Europe);

The WT600 uses edge LED backlighting rather than Panasonic’s famous plasma tech –

So they say "HDMI 1.4 limitations of 4096×2160 at 24fps or 3840×2160 at 30fps which would have put a dampener on fast-paced 4K content like live sports broadcast." Yet they put out a UDTV that is LED based without H.265 support where the motion interpolates only 120Hz. Hmmm.

Sony starts delivering 4K downloads with Video Unlimited 4K service

NEW YORK, Sept. 4, 2013 – Sony today launched the Video Unlimited 4K service, the world's first and only 4K Ultra HD video download service, with access to an expanding library of native 4K Ultra HD feature films and TV shows.

Beginning with a selection of more than 70 full length native 4K Ultra HD feature films and TV shows from Sony Pictures Entertainment and other notable production houses, Video Unlimited 4K will offer customers the option to rent and purchase content for download on Sony's 4K Ultra HD Media Player (FMP-X1) for playback on Sony 4K Ultra HD televisions.

What level of PQ is the first question, what file size? I believe I saw that a 4k stream would require 20 Mbps using H.265 with acceptable PQ. But are the downloads equivalent to a Sony remastered as 4k BD's, upscaled via 4Kx2K (2160p)? After seeing Farscape BD which is just a 576i PAL masters upscaled to 1080P, I get suspicious of Sony billing this as native 4K Ultra HD content.

I find this interesting:

Sony to Support HDMI 2.0 Industry Standard

Sony is prepared to support the HDMI 2.0 specification on its line-up of 4K Ultra HD televisions with an easy firmware update to be available over the Internet by the end of this year.

[JohnAV]

Looking at the Sony 4K media player/storage footnotes.

2 Terabytes equals approximately 2000 Gigabytes. Not all memory is user accessible. Storage of 45 movies is based on average movie file size of approximately 38 GB per movie. Individual movie and video file sizes vary.

Wonder how this will impact ISP caps?

[KillerJuan77]

What about 3D improvements? Any chances for 1080p60 for 3D games?

can the same be done to the playstation 4? so all this is is a firmware update and not hardware?

I'm sure Sony had the heads up on how to prepare to have HDMI 2.0 included in the PS4 when the spec was finalized & this was done months ago.

That's interesting. I would wait for the 4K Blu-ray specification to be announced, before purchasing one of these Sony '4K' sets. I wonder if they adhere to Rec.2020.

This reminds me of when there was 'Ready for HD' and 'Full HD' displays.

But at least this day and age, firmware updating has become the norm for consumer A/V gear.

Good to see all the discussion of HDMI 2.0 indicating Blu-ray movie watchers are also interested in broadcast and sports (4K @ 50/60 fps being almost minimally mandatory). As an aside, my Baltimore Ravens are playing Denver this evening and I’m hoping for the best despite the fact I hear the team’s been gutted in the off season since they won the Super Bowl.

But, on the movie side of things, given that the HDMI 2.0 overview (18 Gb/s) has now been ‘officially’ announced, I find it curious that the video journalists (cnet, etc.) haven’t run the numbers to see if this data rate is sufficient to support 4:2:2 chroma @10-bit per channel. I mean are cinephiles satisfied with 4:2:0 chroma sampling @ 8 bits so a potential (or lack thereof) to upgrade the PQ in this area in the future is of no concern?

What's the point of 32 channel audio? Have you heard of Dolby Atmos or Auro3D 11.1? By upgrading the bandwidth, the possibility of bringing object placement surround is now a lot higher. Previously,we were only limited to 8 channels of audio. Anything more, and we have to settle for a matrix surround format. (Eg. DTS Neo:X)

The upgraded video bandwidth means that 2K/1080p HFR-48FPS 3D(eg. The Hobbit) is now possible at home.

1536 kHz is absolutely crazy at this point. I don't think there's any audio content recorded at that sampling rate.

Yes, all these specs sounds like overkill. But that doesn't mean we're not allowed to expand. There may not be any content that requires such bandwidth now. But the sky's the limit. This means that creative artists has a larger playground to express themselves without being limited by old technology.

The ball's in Blu-ray's court now, with their revision. I really hope to see 4K video, 3D HFR and Discrete 9.1 (or more) surround a reality from here.

Plus, it was easy for the HDMI Forum to do, as adding more channels of audio (and increasing sampling frequency) takes up a relatively tiny fraction of bit rate as compared to 4K video.

It is a concern, but IMHO, Hollywood will resist 10 bit, 4:2:2 and I would wager they will never release anything for consumer use in 10 or 12 bit, 4:4:4. Another problem is H.265, in the first round we only get 8 bit, 4:2:0. Other bit lengths may come with future extensions to H.265. We shall see.

Don't know, IMO, there are very few worthwhile titles available 7.1
